What is the recommended action if there is suspected oxygen supply failure in an anesthesia machine?

• A. Switch to an available oxygen source (portable cylinder), manually ventilate with 100% O2, and contact biomedical engineering
• B. Do nothing and continue
• C. Switch to air mixture
• D. Replace the entire machine immediately

Answer: (A)

When oxygen supply is suspected to be failing, the priority is to maintain oxygenation and ventilation while you troubleshoot. The best action is to switch to an available oxygen source, such as a portable cylinder, and use a bag–valve–mask to deliver 100% oxygen manually. Do this immediately and keep manual ventilation going to prevent hypoxemia as you arrange further help. At the same time, contact biomedical engineering for evaluation and repair of the anesthesia machine so you can restore a safe, continuous oxygen supply. Using air would lower the inspired oxygen concentration and risking hypoxia, and replacing the entire machine right away isn’t typically necessary before securing a back-up oxygen source and ensuring patient ventilation. Doing nothing would be unsafe.
